Here are the requirements I had in mind for this design:
* 6' x 12' trailer--I used the inside dimensions for a Wells Cargo.
* Hubby is 5'10" and I'm 5'5". He may not be able to stretch out completely, but he's a side sleeper anyway.
* Outside galley (accessed via the back doors), with a pass-through behind the dinette that is covered with sliding plexiglass windows. I would attach an awning on the back to shade the galley and protect it from rain.
* Space for two kids, but we usually camp when they are with our exes.
* I didn't put windows in the model--I would want them on both sides of the dinette. Maybe even two small windows on each side, to make it feel more open.
I think we would leave the table down and bed made up most of the time. We camp to spend time outdoors, and don't want to be cooped up in a camper unless it's raining and cold. I put the cupboards over the fixed bunk high enough that it doubles as a seat, and the porta potti will fit in a cupboard under the bunk.
I'm working on another design that doesn't include bunks, so the kids have to sleep in a tent (although I'm not sure if I want to deal with that--my SD would probably have a meltdown).
Any suggestions? What did I forget?
